Understanding Percentages

Before we dive into the calculation, let's quickly refresh our understanding of percentages. The word "percent" means "per hundred." It's a method of expressing a number as a fraction of 100, where "x percent" is literally x parts per hundred.

Calculation:

To find out what 10% of 150 is, you follow these steps:

0.10 * 150 = 15

So, 10 percent of 150 is 15.
